Hi! I used to have arch linux running on 1 btrfs partition (sda1, incl. /boot). When switching to 3.2.5 recently the system fails to boot: (after udevd) /etc/rc.sysinit: line 15: 117 Bus error mountpoint -q /proc and so on, no idea. It used to boot with 3.2.4, but 1) I obviously had some corruption in the tree, when I tried to delete a certain file I hit e.g. "kernel BUG at

commit 8b38694a2dc8b18374310df50174f1e4376d6824 vhost/net: virtio 1.0 byte swap had this chunk: - heads[headcount - 1].len += datalen; + heads[headcount - 1].len = cpu_to_vhost32(vq, len - datalen); This adds datalen with the wrong sign, causing guest panics.

Hi, Does Asterisk support encryption of voice traffic? I found following wiki that describes IAX RSA authentication. I was able to implement the public/private key authentication among three Asterisk servers connected using IAX protocol. I am not certain if voice traffic can also be encrypted among the Asterisk servers. Your help is highly appreciated.
